DETAILED DESCRIPTION OF THE INVENTION

Referring to the drawings and initially to FIGS. 1-3, an external supply system in accordance with the preferred embodiment of the present invention comprises a sensing device 10, and a supply device 20.

The sensing device 10 has a first side provided with a water inlet 11 and a second side provided with a water outlet 12. The water inlet 11 of the sensing device 10 is locked on an outlet 32 of a faucet 30.

The supply device 20 is connected to the sensing device 10. The supply device 20 includes a body 21, a press member 22, an O-shaped sealing member 224, an elastic member 223, and a stop ball 24. The body 21 of the supply device 20 is substantially cylindrical shaped. The body 21 of the supply device 20 has an inside formed with a receiving chamber 210 containing liquid, such as the cleaning agent or the like therein. The body 21 of the supply device 20 has a bottom formed with a drop hole 202 and has a top provided with a transparent cover 201 to facilitate the user replenishing the cleaning agent. The receiving chamber 210 of the body 21 of the supply device 20 has a bottom formed with a connecting hole 212.

The body 21 of the supply device 20 has a lower portion provided with a cylinder 23 having an inside formed with an operation space 230. The operation space 230 of the cylinder 23 has a first side communicating with the receiving chamber 210 through the connecting hole 212 of the receiving chamber 210 and a second side formed with a passage 232 communicating with the drop hole 202 of the body 21.

The press member 22 of the supply device 20 is movably mounted on the body 21 and has a first end 221 protruded outward from the body 21 and a second end 222 slidably mounted in the operation space 230 of the cylinder 23. The second end 222 of the press member 22 has a diameter flush with that of the operation space 230 of the cylinder 23.

The sealing member 224 of the supply device 20 is mounted on the press member 22 to move therewith and is rested on a first side of the second end 222 of the press member 22.

The elastic member 223 of the supply device 20 is mounted in the operation space 230 of the cylinder 23 and is rested on the press member 22 to press the press member 22 to move the sealing member 224.

Thus, the sealing member 224 is driven by the press member 22 to move between a first position as shown in FIG. 2 where the sealing member 224 closes and seals the passage 232, thereby disconnecting the operation space 230 of the cylinder 23 with the drop hole 202 of the body 21, and a second position as shown in FIG. 3 where the sealing member 224 is detached from the passage 232, thereby connecting the operation space 230 of the cylinder 23 with the drop hole 202 of the body 21.

The elastic member 223 of the supply device 20 has a first end rested on a second side of the second end 222 of the press member 22 and a second end rested on a side of the operation space 230 of the cylinder 23.

The stop ball 24 of the supply device 20 is movably mounted in the connecting hole 212 of the receiving chamber 210 of the body 21.

In operation, the press member 22 is initially pressed by the elastic member 223 to move outward, so that the sealing member 224 is driven by the press member 22 to move to the first position as shown in FIG. 2 where the sealing member 224 closes and seals the passage 232, thereby disconnecting the operation space 230 of the cylinder 23 with the drop hole 202 of the body 21, thereby preventing the cleaning agent from flowing outward through the passage 232 and the drop hole 202. At the same time, the stop ball 24 seals the connecting hole 212 of the receiving chamber 210 of the body 21, so that the cleaning agent contained in the receiving chamber 210 of the body 21 will not enter the operation space 230 of the cylinder 23.

On the contrary, when the press member 22 is pressed by the user to move inward, the sealing member 224 is driven by the press member 22 to move to the second position as shown in FIG. 3 where the sealing member 224 is detached from the passage 232, thereby connecting the operation space 230 of the cylinder 23 with the drop hole 202 of the body 21.

At the same time, the operation space 230 of the cylinder 23 produces a pressure to push the stop ball 24 upward during movement of the press member 22, thereby detaching the stop ball 24 from the connecting hole 212 of the receiving chamber 210 of the body 21 and thereby connecting the receiving chamber 210 of the body 21 with the operation space 230 of the cylinder 23, so that the cleaning agent contained in the receiving chamber 210 of the body 21 can enter the operation space 230 of the cylinder 23 through the connecting hole 212.

After the press force applied on the press member 22 is removed, the press member 22 is pressed by the restoring force of the elastic member 223 to move outward, so that the sealing member 224 and the cleaning agent are pressed by the second end 222 of the press member 22 to move to the first position as shown in FIG. 2, thereby squeezing the cleaning agent outward through the passage 232 and the drop hole 202 as shown in FIGS. 2 and 4.

When the sensing device 10 detects existence of an object, the sensing device 10 sends a signal to an electromagnetic valve (not shown) which controls the water to flow outward from the water outlet 12 of the sensing device 10 as shown in FIG. 5, so as to co-operate with the cleaning agent flowing outward from the supply device 20 to wash and clean the object.

Although the invention has been explained in relation to its preferred embodiment(s) as mentioned above, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the present invention. It is, therefore, contemplated that the appended claim or claims will cover such modifications and variations that fall within the true scope of the invention.
